Cacossa, Livingston, N.J., assignor, by mesne assignments, to The Flintkote Company, a corporation of Massachusetts Filed Oct. 39, 1961, Ser. No. 148,536 1 Claim. (Cl. 50-414) This invention relates to an improved outer wall construction and covering and is more particularly directed to a channel type outer wall construction comprising standard fiber board overlapping sheathing shingles and a metal 8 type channel member to which the asbestoscement shingles may be attached to.

In most areas of the U.S., wooden buildings are commonly constructed utilizing a plurality of vertical studs which are usually placed approximately 16" on center, more or less. In the case where it is intended to cover the exterior of the building with shingles, it is customary to first cover the studs with a sheathing material which may be wood, insulation board, gypsum board, plywood, or the like. One of the methods for installing shingles, and particularly asbestos-cement type shingles, utilizes a backer board which is generally thick insulation board. Such a construction permits a substantial shadow line for the asbestos-cement shingle larger than the thickness of the shingle itself.

The present invention relates to an improvement in this art of applying a shingle such as the asbestos-cement type shingle to a side wall in combination with an S shaped channel member placed over the top of one set of shingles and backer board and the bottom portion of the next upper backer board assembly.

It is, therefore, one of the principal objects of the invention to provide an improved wall construction utilizing shingles as the wall covering.

It is a further object of the present invention to provide an improved wall construction utilizing asbestoscement shingles, insulation backer and a supporting S shaped channel member,

It is a further object of the invention to provide an improved wall construction utilizing asbestos-cement shingles, shingle backer and supporting S shaped channel member associated therewith without the need for customary sheathing.

It is a further object of the present invention to provide an improved wall construction utilizing ordinary commercially available asbestos-cement shingles and insulation backer board supported by a supporting channel member which makes them self-aligning.

It is still a further object of the invention to provide additional transverse support for the asbestos-cement shingle midway between standard uprights or studs to assure adequate and strong tranverse wall strength.

A still further object of the invention is to provide wall covering which is sturdy, economical, quick to assemble, and provides an improved type shadow line having esthetic qualities.

These and other objects of the present invention are achieved by the present invention which will best be understood by reference to the drawings which illustrate a preferred embodiment of the invention but it being understood that variations and substitutions may be made within the scope of the claim.

Now referring to the drawings, and particularly to FIG. 1, a perspective cross sectional view of a segment of a wall in accordance with a preferred embodiment of the invention. In the drawing, there are shown studs 11 to which are secured by nails an 8 type metal channel 2 in a transverse direction. The channel 2, although preferably metal, may be extruded from plastic materials and other suitable materials which have strength in both the longitudinal and transverse directions. The channel members 2 are spaced apart in the longitudinal direction of the studs, a distance equal to the vertical height of each individual backer or insulation board 3. The insulation boards themselves are regular rectangularly shaped with square ordinary cuts at their extremities wtih no fancy rabbeted edges, inwardly extending kerfs, or otherwise which previous wall constructions utilized. The insulation board here is preferably /2 thick although it is possible to utilize other thicknesses.

A separate drawing FIG. 2 is shown for purposes of detailing the S shaped channel member 2. In particular, the channel or grooved portions thereof have different widths, one of the grooved sections 4 having a width sufiicient to accommodate the thicknesses of both the asbestoscement shingle and insulation backer board when combined together and the other grooved section 5 having a thickness sufiicient to accommodate only the backer board taken alone. It may be appreciated here that the channel members 2 are each attached to the uprights or studs after a siding assembly of asbestos-shingle and backer-board is adhered to the wall or individually prior to any siding attachments. The channels are attached to the wall so that the narrower groove is away from the studs and facing upward, and the wider groove is close to and in proximity to the wall stud and facing downward.

in assembling the wall the first channel member 2 is attached transversely by nails or otherwise to the lowest part of the wall to start the procedure. Next the insulation board 3 is placed in the groove 5 farthest away from the wall, the channel groove being turned in an upward position to receive the said first backer board, as shown in FIG. 1. The next succeeding channel member 2 is placed over the upper end of the backer board and made to rest along the studs. Here the groove 4, being the wider of the two channel grooves is the portion in contact with the upper part of the backer board. Subsequently the first asbestos-cement shingle 6 is placed over the backer-board so that its upper portion resides in the groove 4 of the second channel member along with the backer member and the lower portion extends without the groove of the first channel and partially beyond to form a distinctive and esthetic shadow line. The backer-board shingle and channel member are then nailed to the stud at the lower portion of the shingle and backer assembly by a ring-shank type of nail 10 as shown in FIG. 3. This procedure then continues progressively as the wall covering is constructed. It maybe appreciated here that it is also possible to construct the wall by first attaching allthe channel members in spaced relation to the studs prior to the attachment of any of the insulation backing or shingle members and then progressively assembling the said backing and insulation members. The procedure followed is strictly a matter of choice.

As previously stated and shown in FIG. 3, the nail is made to penetrate the backer board, the shingle, and the channel member, all three being securely fastened by the nail to the upright stud. In between studs where there is no upright support, the shingle is additionally secured by nailing to the backer board and channel to form a secure integrated support for the shingles. Although the nail does not penetrate the stud, the fact that the channel is there, permits the shingle to have a secure support so that any danger to pulling the shingle out in a transverse or other direction is rather considerably reduced.

It can be seen herein this type of wall construction that there is no need for the usual nailing strips which are placed transverse to the upright studs. Here we have channels which replace the nailing strips and provide for self-aligning of both the shingles and the backer boards. Further, the shingles extend considerably below the channel member and provides a very distinct and esthetic type san ers 3 m3 of shadow line not readily achieved in prior wall construction techniques.

extending upward and the stud. However, it does not penetrate the upper section of the lower backing and shingle assembly. In this arrangement there is no loss of time in causing the nail to penetrate the lower assem bly although the lower and upper portions of the assembly are adequately and forcefully attached to the studs.

'In FIG. 4 the same also applies but here the nail is attached to the shingle, backer-board and channel between the studs but because of the flange 11 of the channel, the shingle and backer-board are securely attached. Because of the strong transverse strength developed by the reinforcing action of the channel, it is also possible to use thinner backing sheaths thereby conserving costs.

It may be appreciated that modifications and changes in construction may be resorted to without departing from the spirit and scope thereof as outlined in the appended claims. As, for example, there is shown in FIG. 5 another type of channel construction 13, having an elongated embossed beaded configuration 14 along one of the longitudinal flanges 15. In this particular configuration, for example, the fiange is reinforced or stiffened transversely the elongated channel to permit greater transverse wall strength, This is particularly important because it allows greater holding power for the ring shank nails holding the asbestos cement shingle since there will be less metal fatigue as the nail is driven through the channel member.

Having described the invention, what is claimed is:

An outer wall construction comprising in combination:

(1) a plurality of spaced vertically disposed studs;

(2) a plurality of hacker boards;

(3) a plurality of facing shingles having a vertical dimension greater than the vertical dimension of said backer boards;
